This preface provides an overview of this guide, describes guide conventions, tells you
where to look for speciÞc information and lists other publications that may be useful.
I
NTRODUCTION
This guide provides the required information to install and conÞgure the Summit1 and
Summit2 Gigabit Ethernet Switch.
This guide is intended for use by network administrators who are responsible for

¥ Local Area Networks (LANs)
¥ Ethernet concepts
¥ Ethernet switching and bridging concepts
¥ Simple Network Management Protocol (SNMP)
If the information in the Release Notes shipped with your Switch differs from the
information in this guide, follow the Release Notes.
T
ERMINOLOGY
When features, functionality, or operation is speciÞc to a particular model of the
Summit family, the model name is used (for example, Summit1 or Summit2).

ONVENTIONS
Table 1 and Table 2 list conventions that are used throughout this guide.

Icon Notice Type Alerts you to...
Note Important features or instructions.
Caution Risk of personal injury, system damage,
or loss of data.
Warning Risk of severe personal injury.
Table 2: Text Conventions
Convention Description
Screen displays This typeface represents information as it appears on the screen .
The words “enter”
and “type” When you see the word “enter” in this guide, you must type
something, and then press the Return or Enter key. Do not press the
Return or Enter key when an instruction simply says “type.”
[Key] names Key names appear in text in one of two ways:
■
Referred to by their labels, such as “the Return key” or “the
Escape key”
■
Written with brackets, such as [Return] or [Esc]
If you must press two or more keys simultaneously, the key names
are linked with a plus sign (+). Example:
Press [Ctrl]+[Alt]+[Del].
Words in
italicized type Italics emphasize a point or denote new terms at the place where
they are defined in the text.
Words in boldface type Bold text denotes key features.

WITCHES
Network managers are currently faced with the challenge of creating networks that can
provide ultra-fast speed and high performance to serve the needs of todayÕs network
users, while simultaneously preserving the investment they have made in Ethernet and
Fast Ethernet technology.
By addressing the entire spectrum of Ethernet data rates (10/100/1000 Mbps), the
Summit family of LAN switches enables you to introduce high-speed Gigabit Ethernet
backbones into your existing network, while maintaining established connections to the
10 Mbps and 100 Mbps segments that already exist.

The Summit family of switches is comprised of two models: the Summit1 and the
Summit2.
Both switches have the following features:
¥ Support for 128K addresses in the Switch forwarding database
¥ Fully nonblocking operation
Ñ All ports transmit and receive packets at wire speed
¥ Autonegotiation for half- or full-duplex operation
¥ Optional redundant power supply
¥ Redundant physical Gigabit Ethernet backbone connection
¥ Virtual local area networks (VLANs) including support for 802.1Q
¥ Quality of Service (QoS)
¥ Spanning Tree Protocol (STP) (IEEE 802.1D) with multiple STP domains
¥ Wirespeed Internet Protocol (IP) routing via Routing Information Protocol (RIP)
version 1 and RIP version 2
¥ Integrated network management
¥ Console connection
¥ Telnet connection
¥ Web interface
¥ Simple Network Management Protocol (SNMP) support

ONNECTIONS
The Summit1 provides eight Gigabit Ethernet ports. Six of the ports are Þxed
1000Base-SX ports using 850nm duplex SC connectors. Two of the ports are modular,
and support the standard Gigabit Interface Connector (GBIC). This enables you to select
various types of Þber and copper modules to support longer distances or lower cost.
The Summit1 can be ordered with either two 1000Base-SX or two 1000Base-LX GBIC
transceivers already installed. GBIC transceivers can also be ordered separately.

The Summit2 is a workgroup switch featuring sixteen 10Base-T/100Base-TX ports, two
Gigabit Ethernet uplinks, and one redundant Gigabit Ethernet uplink. The
10Base-T/100Base-TX ports use standard RJ-45 connectors. They are autosensing for
10/100 Mbps operation, as well as half- or full-duplex operation. The Gigabit Ethernet
interfaces support the GBIC connector, and ship with standard 1000Base-SX, 850nm
GBIC modules. Additional cable types are also supported.

FULL-DUPLEX
The Summit Switch provides full-duplex support for all ports. Full-duplex allows
frames to be transmitted and received simultaneously and, in effect, doubles the
bandwidth available on a link. All 10/100 Mbps ports on the Summit autonegotiate for
half- or full-duplex operation.
PORT REDUNDANCY
The Summit2 has an optional redundant Gigabit Ethernet port. Using the redundant
port, you can dual-home the Summit2 to one or two Switches. Figure 1-3 illustrates a
Summit2 dual-homed to two different Switches.
Figure 1-3: Dual-homing configuration
In the event that the active port fails or loses link status, the redundant port is
automatically activated. When the primary port resumes operation, the redundant port
becomes inactive. The redundant port cannot be used for load sharing.
VIRTUAL LANS(VLANS)
The Summit has a VLAN feature that enables you to construct your broadcast domains
without being restricted by physical connections. Up to 255 VLANs can be deÞned on
the Summit. A VLAN is a group of location- and topology-independent devices that
communicate as if they were on the same physical local area network (LAN).
Implementing VLANs on your network has the following three advantages:
